# Changelog

All notable changes to Jarl are documented here. The format follows
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and versions follow
[Semantic Versioning](https://semver.org/).

## [Unreleased]

The first version, to be released as 0.1.0.

### Added

- **jarld daemon**: REST API (`/api/v1`) and embedded web UI, with SQLite as
  the source of truth for the whole BIND configuration. Runs under systemd
  (`Type=notify`, sandboxed, unprivileged `jarl` user in group `bind`).
  SIGHUP and certificate file changes reload TLS.
- **Configuration model**: views (ordered, match-clients/destinations,
  recursive-only), ACLs (nested, negation, keys, reference tracking with
  rename and delete protection), TSIG keys (kept in a separate `keys.conf`,
  never in diffs), zones of every type (primary, secondary, stub,
  static-stub, forward, mirror, hint, redirect, in-view), reverse zones
  from a CIDR, records of every type, options at server, view, zone and
  top-level scope, and defaults for new zones.
- **BIND 9.20 option catalog**: all 353 statements with grammar, allowed
  scopes, value kinds, deprecation status and ARM descriptions, used for
  validation and by the UI's option editor.
- **Changesets**: immediate one-operation changes by default; staging into
  named changesets (`?changeset=`, `X-Jarl-Changeset`, `--changeset`),
  batches (`POST /apply`, `jarl apply -f`), dry runs, previews with diffs,
  and revert of applied changesets. Optimistic locking with object versions.
- **Apply pipeline**: whole-configuration validation, rendering, `named-checkconf -z`
  and `named-checkzone` in a staging directory, atomic install, `rndc reconfig`
  and per-zone reload, verification with `rndc zonestatus`, and automatic
  rollback when named doesn't load the change. Automatic serials (date,
  increment or unixtime policy, RFC 1982), bumped only when DNS data
  changes. Drift detection for files changed outside Jarl.
- **Validation**: CNAME/DNAME rules, NS/MX/SRV targets, glue and
  delegations, RRset TTL consistency, BIND 9.20 RRset/type limits, SPF/DMARC
  sanity, ACL/key references and cycles, option syntax and scope, and
  security lints (open resolver, open zone transfers, dynamic updates on
  managed zones).
- **Records**: TXT entered as plain text (automatic quoting and 255-byte
  splitting), relative and absolute names with detection of doubled
  origins, PTR records kept in step with A/AAAA (`ptr`), RRset replace,
  delete by match, zone file import (merge or replace).
- **Import and adoption**: `jarld import` reads an existing named.conf tree
  and zone files (comments, `$INCLUDE`, `$GENERATE`, legacy
  `master`/`slave` spellings); `jarld adopt` switches named to Jarl's
  configuration with a backup and automatic fallback.
- **Authentication**: web logins with argon2id passwords, sessions
  (HttpOnly, SameSite=Strict) and CSRF tokens, rate limiting per user and
  IP; hashed API tokens (`jarl_...`) with optional expiry.
- **Permissions**: granular grants (resource × read/write, filtered by zone,
  view, record name pattern and type), roles (`readonly`, `dns-editor`,
  `operator`, `acme`), tokens restricted to a subset of their user's
  rights, administrators.
- **Audit log** of logins, changes, users, tokens and secret reveals, with
  user, token, IP and outcome, searchable and written to the journal.
- **Web UI**: dashboard, zones and records with inline editing and pending
  markers, views, ACLs, TSIG keys, the option editor, review and apply,
  history with revert, audit log, users, account and tokens, search.
  Review mode by default, with an "apply immediately" switch.
- **jarl CLI**: zones, records, views, ACLs, TSIG keys, options, settings,
  changesets, batches, history, users, tokens, audit, search, status, check
  and resync. Table, JSON and YAML output, and documented exit codes.
- **ACME DNS-01**: `jarl acme set|unset`, certbot hooks
  (`jarl acme certbot-auth|certbot-cleanup`), an acme.sh DNS API hook
  (`contrib/acme.sh/dns_jarl.sh`), automatic zone and view discovery,
  idempotent retries, and `--follow-cname` / `--resolver` for a dedicated
  ACME zone.
- **Operations**: `jarld backup` (online), `jarld resync`, `jarld check`,
  `jarld render`, local user recovery commands, audit retention.
- **Packaging**: Makefile (build, test, e2e, install, dist), systemd unit,
  sysusers.d and tmpfiles.d files, example configuration
  (`jarld config --example`).
- **Tests**: unit tests for every package, integration tests against the
  real named 9.20 (checkers, reload and rollback, import and adopt), and an
  end-to-end script (`scripts/e2e.sh`) that drives every CLI command
  against a running named.
- **Documentation**: concepts, install and adoption, configuration, CLI,
  API, permissions, ACME, validation, operations and development guides.
